iOS Question App crash while using audio play

[IamTrying]

I have to play a ring.wav file when the app is active or in backend, following works but app crashed. Any idea if the crash can be avoided?
I have applied the try catch now before it was not.

Sub playAudio()
    Try
        NativeMe.RunMethod("setAudioSession", Null)
        vv.Initialize("vv")
        vv.LoadVideo(File.DirAssets ,"ring.wav")
        vv.Play
        NativeMe.RunMethod("register", Null)
       
    Catch
        Log(LastException)
    End Try
End Sub

#If OBJC
@import MediaPlayer;
#import <AVFoundation/AVFoundation.h>
#import <AudioToolbox/AudioToolbox.h>
- (void)setAudioSession {
  AVAudioSession *audioSession = [AVAudioSession sharedInstance];
  NSError *err = nil;
  BOOL success = [audioSession setCategory:AVAudioSessionCategoryPlayback error:&err];
  if (success) {
  success = [audioSession setActive:YES error:&err];
  }
  if (!success)
  [NSException raise:@"" format:@"Error setting audio session: %@", err];
}
- (void)register {
   MPRemoteCommandCenter* center = [MPRemoteCommandCenter sharedCommandCenter];
   center.playCommand.enabled = true;
   center.pauseCommand.enabled = true;
   [center.playCommand addTarget:self action:@selector(play)];
   [center.pauseCommand addTarget:self action:@selector(pause)];
}
- (void) play {
   NSLog(@"test");
   [self.bi raiseEvent:nil event:@"controlevent:"  params:@[@"play"]];
}
- (void) pause {
   [self.bi raiseEvent:nil event:@"controlevent:"  params:@[@"pause"]];
}

#end if

Try this - might help - I'm open to other suggestions:

Sub Process_Globals
     Dim ping As MediaPlayer
End Sub

Sub PlaySound
    ping.Initialize(File.DirAssets,"ring.wav","")
    ping.Volume = 1
    ping.Play
End Sub
